players are more responsive to your efforts depending upon who else they are interested in, and, I believe as more evidence comes in, even who else is contacting (putting in effort) even without showing as considering. It is likely that if the 193 guy wasn't considering the DI all along that D I was putting in effort at the same time you were, leading the recruit to be less appreciative of your efforts. Also, there is a random element as well I believe, so that even without any outside influence you still might get the same result, lower ranked kid ignores you, etc...
